You're welcome :)
Glad it worked!
According to this document, page 67, it seems that the option is only for A4 & Letter.
Sorry, but this machine may not take SRA3 Transparent.
Should not be a problem.
If you try changing the paper settings to transparent paper, will that help?
It is not recommended to print on any paper that is less than 60 grams, I guess the tracing paper you use is very thin?
